Answer:
here are three basic categories for fire alarm panel signals: trouble, supervisory, and alarm. Trouble Signal. A trouble signal is typically designated by a yellow light and means that there is an operational issue. For some more advanced systems, the panel may indicate the kind of problem and where it is located.
Explanation:
Answer:
Company A
The ISO 27002 classification level that is most likely assigned to this document is:
b) Proprietary
Explanation:
The ISO 27002 classification levels adopted by commercial organizations are Restricted (top secret is preferred in government circles), Confidential, Internal (or proprietary), and Public. Since the new product is under development, one of many, and most likely known to the project team, the project plan will be classified as Proprietary. Company A designates this document as Proprietary or Internal to show that disclosure of the information to its competitors is not allowed. This level of classification shows that Company A can establish intellectual property rights over the document.
Answer:
The answer is "Option b"
Explanation:
In the given code three-class C1, C2, and C3 are declared, in which C2 and C3 extend the class C1. In the next line, C2 and C3 object are created, that is c2 and c3. and in the last line c2 class object holds two-class C2, C1, and one object c3 value, this code will give runtime error because it can't cast object from sibling class, and wrong choices can be defined as follows:
- In option a, It is not correct because it can't cast c3 object into c2 object.
- In option c, It is not correct because it performs multiple casting in nested forms.
- In option d, It is wrong because the statement is not correct.
Answer:
Option 4: Different programming languages are better for different functions, and new programming languages are being written all the time.
Explanation:
All programing languages are best in their own perspective. Some are easy to handle while other have a smart but tricky context. Therefore different languages are suitable for different functions.
Functional Programming is the term depicting the modularity of code. In actual, it deals the data and functions as immutable. Which means the program state is never changed, the data you pass into the function is returned in a transformed form but actual data is not changed. Not all languages offer functional programming, the top languages which are better with such features are:
- Java Script
- Python
- C++
Moreover, new programming languages are being written for more and more convenience and ease. They are being introduced day-by-day because:
- There is a need of new features.
- Flaws in previous languages.
- More functionality is needed in smaller time.
- Code needs to be more and more smaller.
